Protection Engineer 400kV Switchyard

Key Responsibilities: 1 Protection System Design & Coordination: Design, review, and implement protection schemes for 400kV switchyards . Configure and program numerical relays (Siemens, ABB, GE, Schneider, SEL, Alstom, etc.) . Perform relay coordination studies to ensure selectivity and system stability. Develop and implement protection logic diagrams, settings, and interlocking schemes . 2 Testing & Commissioning of Protection Equipment: Conduct testing and commissioning of: Distance Protection (Zonal Protection, Carrier Aided Trip, Power Swing Block) Differential Protection (Transformer, Line, Busbar, Reactor Protection) Overcurrent & Earth Fault Protection Breaker Failure Protection, Synchro-check, and Auto Recloser Relays Perform Primary and Secondary Injection Testing using Omicron, Doble, or Megger test kits. Verify Current Transformer (CT) & Potential Transformer (PT) ratios, polarity, and burden calculations . Conduct circuit breaker timing tests and SF6 gas monitoring . 3 Fault Analysis & Troubleshooting: Analyze fault records, relay event logs, and disturbance reports to identify root causes. Investigate grid disturbances, tripping events, and blackout scenarios . Coordinate with Grid Operators, Load Dispatch Centers (LDCs), and System Control Units for system restoration. 4 Documentation & Compliance: Maintain records of relay settings, test results, and protection coordination reports . Prepare testing & commissioning protocols, SAT (Site Acceptance Test) reports, and relay configuration documents . Ensure compliance with IEC 61850, IS, IEEE, and Grid Code requirements . 5 Safety & Reliability: Ensure adherence to LOTO (Lockout-Tagout) procedures before testing or maintenance.
